AVR AS480 Automatic Voltage Regulator for Generator P044 and P144 Industrial and Marine alternator

AVR AS480 Automatic voltage regulator for generator P044 and P144 industrial and marine alternatorsAVR AS480 is using on P044 and P144 industrial and marine alternators. AS480 is equipped with a overexcitation shutdown, the AVR is constantly monitoring the exciter field and will provide the required signal to collapse the output voltage if needed. P044 Series Alternator includes:PI042D PI042E PI042F PI042GP144 Series Alternator includes:PI144D PI144E PI144F PI144G PI144H PI144J PI144K PM144D PM144E PM144F PM144G PM144H PM144J PM144K PART NUMBER: E000-14808/1PThe AS480 AVR is a half wave phase controlled AVR which forms part of the excitation system of the brushless generator. The design employs Surface Mount Technology (SMT), custom mouldings and heatsinks to produce a compact AVR assembly. The AVR also incorporates an interface to the optional Excitation Boost System (EBS) for use where short-circuit current maintenance is required.The Automatic Voltage Regulator AS480 is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%. The AVR voltage sensing terminals continuously sample the output windings for voltage control purposes. In response to this sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR AS480....
